IMPROVEMENT |N SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 131,253, datedSeptember 10, 1872.

To all whom it may concern:

Be it known that I, J. M. GULLEY, of J efierson, inthe county of Greenand State of Iowa, have invented a new and Improved Seeding Attachmentfor Cultivators; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming part of this specification, in which Figure1 is a perspective view of the attachment partly broken away to show theconstruction, and Fig. 2 is a front view of one of the grain-feedersdetached from the hopper.

Similar letters of reference in the accompanyin g drawing denote thesame parts.

My invention relates to that class of seedingmachines in which a seriesof feed-wheels are placed within a hopper to lift and discharge thegrain therefrom when rotated andhas for its object to improve theconstruction of such machines, whereby they are rendered more completeand efficient in operation. To this end the invention consists, first,in inclosing each wheel within a separate compartment whose upper halfis adapted for removal, the grain being fed to the wheel beneath thewalls of the compartment only. By this construction the hopper can becompletely filled with grain without interfering at all with themovements of the wheels, while the latter are accessible for adjustmentor repairs by removing the upper portions of the compartments. Itconsists, secondly, in the construction of the devices by which thegrain is fed from the hopper to the wheels. It consists, thirdly, in thecombination of the feeding devices and p the seed-slides with theinclosing compartments and the feed-wheels, as I will now proceed todescribe.

In the accompanying drawing, A is the hopper of a seeding machine, and Bthe feedwheels, mounted at intervals upon a horizontal shaft, 0,havingits bearings in the ends of the hopper. in a narrow transversecompartment composed of lower fixed walls or partitions D, which affordadditional bearings for the wheel-shaft, and upperremovable sections orboxes E, which fit over the wheels and extend to the top of the hopper.The removable sections rest snugly upon the walls D, and are held inplace against lateral displacement by fitting their open ends 'partmentsof the liftingwheel. wheels B are constructed with a series of pe- Eachof the wheels is containedin front of the seed-tube J, while the armspass each side of such tube through the front of the hopper, as abovedescribed. By moving the slides through the front of the hopper the sizeof the feed-openin gs is adjusted to regulate the quantity of grain fedto thelifting-wheels. K K are cams pivoted to the front of the hopper soas to be turned against one arm of each slide for the purpose of holdingthe latter in the desired position. L are the feeders, mounted atdifl'erent angles upon the shaft 0, in close proximity to the outside ofthe compartmentwalls. They are each composed of a bar of wood or metal,having beveled edges extending about half their length upon oppositesides.

These beveled or sharpened edges are made in the form of a reversecurve, m, as shown in Fig. 2, the outer portion of the curve being flushor nearly so with the flat side a of the bar. By this construction, whenthe shaft is rotated the'bars not only stir the grain in the hopper butforce it with a pushing action through the feed-openings 9 into the com-The feedripheral shoulders, 0, upon which are arranged curved plate P,secured in place by the removable bolts or set-screws q. By thisconstruction buckets or seed-cups are formed upon the wheel, as shown,to lift the requisite quantity of grain. I design to supply the machinewith two or more sets of seed'cups, the several sets differing in sizesomewhat, and to substitute one set for another when it becomesnecessary or desirable to change the quantity of seed to be sown.

When the machine is in operation with the hopper filled and thecompartments closed, the rotation of the shaft 0 causes the bars L tofeed the grain into the wheel-compartments, where it is taken up by thebuckets and discharged into the seed-tube through the openin gs R in thefront of the hopper. By constructing the hopper with compartments, asabove described, the feed-wheels are rendered accessible for repairs,850. The hopper can be completely filled with grain without obstructingthe movements of the feed-wheels, because such grain is fed to thewheels at the bottom of the compartments only.

Having thus described my invention, what I claim is- 1. The closedcompartments for the feedingwheels, consisting of the fixed walls D andthe removable box F, arranged transversely of the hopper A,substantially as described, for the purpose specified.
